I looked at the Web site again, and now it was all clear. Perhaps I was
mentally drunk or something at the time I first checked it. Sorry.
However, it's funny how they lie in the actual README ;-)

I'm trying to do a search-and-replace for a certain string (#1) from a bigger string (#2), take that string (#1), do an SQL search, then do a little fiddling to make another string (#3), and put that string (#3) back into the big string (#2) to replace the certain string (#1).
Here's what I need. I have a string such as this:
"Yadda yadda yadda yadda '32'(l) yadda yadda yadda '2'(l) yadda '419'(l)." (#2)
I need to find the strings like '32'(l), '2'(l), and '419'(l), including the single quotes. Basically a '[0-9]*'(l). This is #1.
Take that string, look up a record in an SQL table based on the number in the single quotes. Take a field in the record (#3) and replace #1 with it. So basically, we have:
"Yadda yadda yadda yadda supplanted-string yadda yadda yadda supplanted-string yadda supplanted-string." (#2)
I really hope I'm explaining this properly, and after a few attempts, I have no clue where to restart. Does anyone have any ideas how to do this?

It seems preg_replace_callback() would be ideal for this job.

Hello,
I'm having a real frustrating time with my problem here, which is to copy one JPEG to another resource. I'm not even sure where I'm going wrong, or how to find it out, because it seems that I'm getting all my resource IDs fine (when I echo them, I get 'resource ID #x'), and no error message pops up. Just a broken image is produced. I've been racking myself for so long now that my problem may be right under my nose, but my brain is so baked it's just not working. And I've tried to leave and come back to it, but... you know how it is. Here's what I'm doing.
What I'm trying to do is copy one JPEG to another JPEG (as mentioned) on the fly. I don't want to have a new file produced, just a modified JPEG (a few circles here and there) held in a resource. Here's how I call my function and how I display the image via HTML:
print("<IMG ALT... HEIGHT... WIDTH... SRC = \"" . copy_pic($sourcepic) . "\">");
So I'm calling the function straight from the SRC attribute of the IMG tag. Here's what's in my function:
function copy_pic($sourcepic) {
if(file_exists($sourcepic)) {
$destinationpic = imagecreatetruecolor(imagesx($sourcepic), imagesy($sourcepic));
imagecopy($destinationpic, $sourcepic, 0, 0, 0, 0, imagesx($sourcepic), imagesy($sourcepic));
}
return $destinationpic;
}
After this, I'm going to be tampering with the pic, but I just wanted to make sure I'm getting something, which I'm not. All I get is a broken image. No error message, no nothing. Please tell me I'm not overlooking some really idiotic thing, but I'm just having one heckuva time with this.
Thanks, everyone.

SRC is supposed to be a URL ...

Not idiotic at all.
You have to sort of "un-learn" something, and wrap your brain around a new
concept. :-)
You know how PHP spits out HTML?
Yeah, well, PHP doesn't *just* spit out HTML.
PHP can *also* spit out an actual JPEG.
Like, it spits out what you would get if you opened up a JPEG in a text
editor and you see all that gobbledy-gook.
But to do this, you've *still* got to have it being spit out as *JUST* the
image, in a separate file, the *same* as having a separate JPEG image file
on the server which is not all that gobbledy-gook pasted into your HTML.
Or, to put it this way:
You currently have something like this all in one big file:
<HTML><BODY>
...
<IMG SRC=JPEG%(**&^##R%GFGE#WWRYUIIUUYY**&%*&%$^&%$#%^#%$#%$^%$##$#%$^%>
...
</BODY></HTML>
But, a valid setup would have *TWO* files. One with:
<HTML><BODY>
<IMG SRC=otherfile.jpg></HTML>
</BODY></HTML>
otherfile.jpg would have the JPEG stuff in it:
JPEG%(**&^##R%GFGE#WWRYUIIUUYY**&%*&%$^&%$#%^#%$#%$^%$##$#%$^%
So you need to move your copy_pic stuff and all of that to a DIFFERENT
file, say "dynamic_jpeg.php".
Your HTML will then have:
<IMG SRC="dynamic_jpeg.php">
in it.
Plus your dynamic_jpeg.php file will have to have this stuff at the end:
header("Content-type: image/jpeg");
imagejpeg($destinationpic);
PS: You may not be *SEEING* the error messages, because they are buried
in the contents of what is supposed to be a JPEG. But if your JPEG looks
like this:
JPEG*(&*^*&^%^&% PHP Error: blah blah blah *&*&^%$$###$%^^^
then it's just a broken JPEG, as far as the browser is concerned.
So surf *DIRECTLY* to it when the browser shows you a broken image icon:
http://sympatico.ca/dynamic_jpeg.php
for example.

But isn't the "next value" of $option controlled by the outer while-loop?

So inside the inner while-loop, $option should never change.

No. But I can tell you that:
1) the reset() aren't necessary
2) even better, use a foreach-loop instead of while-loop

Hi Jason:
Thanks for the reply.
I added some of the reset in just to make sure the pointer isn't somewhere
else through earlier iterations/to make sure it doesn't make a difference.
Will play around with the foreach as soon as I have some time. Reading
through php.net it seems like there are a few pitfalls (as there can be with
while) to watch out for.
Found out what the problem was after I posted. Reading through the function
manual for each I found the following:
<snip>
Caution
Because assigning an array to another variable resets the original arrays
pointer, our example above would cause an endless loop had we assigned
$fruit to another variable inside the loop.

That's what I did. Didn't had to but it has been a copy and paste from some

Hi,
I have an html file containing a table. I applied
eregi("<TR>.*</TR>",$contents,$temp) through my Php.I am getting
the output like this-
<td>A</td><td>B</td></tr>
<tr><td>C</td><td>D</td></tr>
<tr><td>E</td><td>F</td>
But my expected output is -
<td>A</td><td>B</td>
<td>C</td><td>D</td>
<td>E</td><td>F</td>
The code removing only the first and last <(/)tr>.
How to do it using eregi ? (or using any other regular expression function. I don't want to use any string replace function.)

Expected behaviour : regex are 'greedy', ie
the .* matches the longuest string possible
> How to do it using eregi ?
Use preg_* functions (Perl regex are more powerfull and faster)
ex (not tested)
$temp = preg_replace('/<tr>(.*?)<\\/tr>/', '$1', $content);
PS the '?' in '.*?' means previous modifier (*) is not greedy
(Perl re syntax, man perlre)

I', sorry if my previous email not that clear, I'm
making a simple web-base inventory using PHP, and I
don't know how to using a web form to :
1. delete multiple raw by input an uniqID (in this
case UserID, say there was five users)
2. after deleting it, there will be say six users need
to add.
3. and I make delete or add by uploading file that
contain data I need ?
And all I hope can do by a web-base application using
PHP
sorry If I can't make it clear in my previos posting

Hi!
Last help about regexp solve my problem, but I have another one.
I've made some regexp but it does not work always
Let say I have some strings
1) this is some domain.com test
2) domain.com
I can make this work either for first example of fo second, but not for
both. What I want is replace of domain.com to get
this is dome domain.com domain com test so replace should be
\1 \2 \3
so for second example I did /((.+)\.{1}(.+))/
How can I extend this to work in both.

attached mail follows:
You could maybe cheat and add an X at the beginning and end of the string
before your Regex, then you will have:
X\1 \2 \3X
and you can strip off the initial X from \1 and the trailing X from \3
There's probably some fancy Regexp way to do it though.

My experience dictates the contrary.
Apache 2 is much faster with PHP that Apache 1.3. I run an enterprise
web application in my company with about 950 users concurrently. I
configured the apache logs to add the execution time for each request
(this is done with %T in the LogFormat). We started the production
system around 2 years ago with RH9 and Apache 1.3. Only 72% of the
requests scored 0 seconds (which means less than 1 second). Then I
updated to Fedora Core 2 with Apache 2 and it scored 96%.
I know the kernel is a lot better but this improvement is almost because
of Apache 2 since I tested Apache 1.3 in the same system and I got back
to the 72% performance.
I guess this dependes of what you use. Because PHP has an Apache filter
and an Apache handler. I use the later.

Rasmus,
I see much better performance with Apache 2. I'm not an expert in the
internals of Apache nor PHP but I guess one of the improvements in
apache is the log mechanism, I think it use a different technique that
makes it faster that Apache 1.3
The reason I say this is because Apache 1.3 log are written in perfect
order according to the time field. I Apache 2 the logs are not ordered
so you can have something like this:
172.20.15.138 - - [06/Jan/2005:09:43:55 -0500]
192.168.149.42 - - [06/Jan/2005:09:43:55 -0500]
192.168.150.27 - - [06/Jan/2005:09:43:55 -0500]
172.16.113.22 - - [06/Jan/2005:09:43:53 -0500]
192.1.20.197 - - [06/Jan/2005:09:43:54 -0500]
192.168.172.20 - - [06/Jan/2005:09:43:55 -0500]
192.168.150.66 - - [06/Jan/2005:09:43:55 -0500]
This is extracted from my production server with FC3 Apache 2.0.52 and
PHP 4.3.9

This is great. In my high performance web app I created a PHP library
that abstracted this to use several backends. For instance I have a
File backend and a SHM backend that uses the functions provided by the
sysvshm PHP module. With this functions, do they need to
serialize/unserialize every time I put/get something in/from the cache??
Also I use sysvsem for locking capabilities. does apc take care of the
locking? does it have an API to do that?
My experience with shared memory have been great. My production server
uses a segment of 384MB to cache lots of resultsets and PHP objects and
the performance is almost unbeatable... well if it serializes then
pecl/apc will give better performance I guess.

Call me crazy or ignorant, i'm both, but would it be possible to build
an extension that, in its MINIT hook as you suggest, actually runs a
separate PHP script that contains global definitions, then makes those
definitions available to later scripts? this is basically my original
desire of having a one-time, persistent global include for each apache
process. i realize you suggest pulling array data from a source like a
DB or XML file, which would be a 90% solution for me, but the next step
(a PHP script) just seemed logical/exciting...
i realize i'm reaching with this, and it implies a conundrum (how does
an extension run a PHP script if PHP hasn't fully started yet) but this
kind of thing is just what makes me go and learn new things (C, php/zend
internals) and I just might try to do it if it was feasible, for the fun
of it, because it could be useful to lots of people, even if it took me
a year or two to pull off.
alas, this is a question for the pecl-dev list.

If you are doing this in user-space PHP, then yes, you will have to
serialize.

APC takes care of locking and all cache management.

Additionally you can check the access time to see which of those
sessions has been accessed in the last, let's say, 10 minutes or
something.
But there are several problems with this. Relying on session files is
not good enough, they might be stored in a database or in shared memory.
Other problem is that those sessions are for every PHP app installed in
the server so you are counting sessions for different apps like it were
from yours.
To solve this you could put some APPID in the session and check for its
value reading the sess file as text. Obviously you will have to figure
out the format a little bit.

You are missing error checking on the openssl_pkey_new() and
openssl_csr_new() function calls.
You don't even know for sure that you have a valid PKEY nor that you have
a valid CSR resource.
And, of course, you should have some error-checking on the return value
from openssl_csr_sign() to see if it worked.
Odds are really good that if you add all that error-checking, and the code
needed to find out what error occurred --
http://php.net/openssl_error_string -- you'll find out that the OpenSSL
software and PHP have conpsired to tell you *exactly* what is going wrong.
:-)
My first Wild Guess would be that your PHP user doesn't have permission to
read your .crt and .key files, or that you don't have a PHP-readable valid
openssl.cnf file.
If all else fails, despite the examples in the manual, you may want to try
to get rid of the 'file://' parts of your file names. But maybe you need
those for some arcane OpenSSL reason beyond my ken. [shrug]

Richard,
Actually, if you leave the code exactly as-is, but change the
openssl_csr_sign function to create a self-signed certificate, the
entire script executes perfectly. I know there is a lot of error
checking needed - I'm just making a "test" script to get a feel for how
OpenSSL operates in PHP. The certificate and key files are mode 444
(readable by everyone) as they are just "test" certificates right now.
I have a valid openssl.cnf file (in /etc/ssl/openssl.cnf, which is
what's complied into OpenSSL) and I use that configuration file that I
use with some shell scripts to do everything that I want to do in PHP,
so I'm sure it's a valid openssl.cnf file.
Does PHP restrict access to /etc/ssl for the OpenSSL library if I have
open_basedir set? Perhaps I need to make an openssl.cnf in the
/usr/home/ws1086 (which is the open_basedir path) so that it's readable?
I would think that the library would have access to the whole system
since it's not really part of PHP, but maybe I'm wrong.
Either way, it's not complaining about access to openssl.cnf, it's
complaining about access to the certificate, so let's take it one step
at a time. :)

Let me ask you this. Do you know what underlying libraries are
associated with the extensions you want to use (in your list below)? If
you do then you *should* be able to google for each library individually
and see if that library is thread safe. I have not gone through this
exercise for myself, but then again I don't need to either. ;) This
would also be something that would be a great benefit to share with the
PHP community if you decide to compile this list of thread-safe extensions.

I have read somewhere that this is true, but I have absolutely no
firsthand experience in PHP's source to tell you if this is the case.
Rasmus will know (whistling and walking away...)

Yes it does... IIRC check out TSRM in the source.

I have no idea. ;) But I use a lot of these functions as well and it
would be good to know.

To anyone reading this, remember he's using PHP 4.3.x but he's asking
about PHP 5.x. So I guess the question there: is libxml2 thread-safe?

Good lord I would hope so :)

All of the XSL stuff should fall under the umbrella of "is libxml2
thread safe?" since we use that library for XSL functionality too.
One final note. I notice that you make of the PHP4 XML libraries?
Well, there was a break in this functionality in PHP5. If you used the
"almost W3C compliant" domxml functions then you should be ok. If not,
well, you might be in for some rewriting there. :(
